Will stations always be stuck with 1% digital power, or even 10% digital power, or will they, perhaps after their hybrid phases end, be able to resume operation at something more akin to their analog power levels? Maybe better receivers will help, but I am disappointed with the decreased range of the AM's and HD2's to which I listen.

There is no decreased range with IBOC. Just ask iBiquity. They'll tell you straight out.

The FM HD2 should have the same "range" as the main since it is the same data stream. Any station could go full digital right now but none are that insane, considering the consumer adoption rate. I'm still waiting for one of the incessant whiners who insist AM is dead to try one in digital-only mode at full power.
